PHP Code:

<?

$arr = array(

"One" => array("One" => "1,1", "Two" => "1,2"),

"Two" => array("One" => "2,1", "Two" => "2,2")

);

echo $arr["One"]["Two"]."
".$arr["Two"]["Two"]."
";

echo $arr[0][1]."
".$arr[1][1]; //line 13
?>

produces

1,2
2,2

Notice: Undefined offset: 0 in c:\Inetpub\wwwroot\array.php on line 13

Notice: Undefined offset: 1 in c:\Inetpub\wwwroot\array.php on line 13
